When I was working on the page "Introduction", I found out that Cinelab, actually, was nothing more than a section of the Practiphone, implying their production which is based on movie and TV films. So, I have corrected some of my early posts in this topic to that they do not mislead you if you decide to read the topic from the very beginning.

Practiphone had other sections too, the largest was Teatro español.
It seems, that is according to what I found for a current moment, educational institute of languages, Practiphone, have started producing brochures with audiocassetes based on films, stage productions, etc, since the 1970. Before, they released only products related directly to the study of English (although they were also closely involved in teaching French). The earliest mention of the Practiophone I found in 1962, when this was as Club._________________Russian fan-site Steedumbrella.
